48 STALK- AND SESSILE-EYED CRUSTACEA 
52. Pinnotheres pisum. 
Cancer pisum, Linn, Syst. Nat. ed. xii, p. 1039, (1766). 
Pinnotheres pisum, Latr. Hist. Nat. Crust. vi, p. 85, (1808); M. 
Edw. Hist. Nat. Crust. ii, p. 31, (1837). 
Pinnotheres mytilorum, M. Edw. Ann. Sci. Nat. (ser. 8) xx, p. 217, 
pl. x, fig. 1,.(1853). 
Carapace soft. Front prominent in the male, not projecting beyond 
the curved line formed by the front part of the carapace in the female. 
Lower margin of the hands ciliated. Abdomen of the male with the 
last joint smaller than the penultimate, of the female circular. Length 
and breadth of ? about $in. (M. E.). 
Auckland (Heller); New Zealand (Coll. Brit. Mus.). 
Dr. Heller (Voy. Novara, Crust. p. 67) states that he is unable to 
distinguish the specimens of Pinnotheres collected at Auckland from 
the common European species, with which they agree in the form of 
the carapace, anterior legs, outer manxillipeds, and abdomen, the only 
difference being that the fifth pair of legs is a little less hairy in the 
New Zealand specimens. The same is true of two female examples 
from New Zealand in the Collection of the British Museum, Dr. 
Heller further observes that the specimens from Auckland inhabited 
shells of the genus Mytilus, as is commonly the case with the European 
species. Iam informed by my friend, Mr. E. A. Smith, that the New 
Zealand Mussel is not even to be distinguished specifically from the 
English one—an interesting fact, which confirms Dr. Heller’s observa- 
tions on the Pinnotheres. 
53. Pinhotheres latipes. 
Pinnotheres latipes, Jacquinot and Lucas, Voy. Pole Sud. Zool. i, 
Crust. p. 57, pl, v, fig. 16, (1853). 
Carapace broader than long, convex, smooth, front wide, truncate. 
Byes very small, Aniterior legs robust, elongate, with the third and 
fourth joints canaliculate, hand smooth, mobile finger with a tubercle 
near its base, lower finger with a tubercle at its base. Ambulatory 
lees broad, compressed, and (apparently) canaliculate. \(J. & L.). 
New Zealand, Raffles Bay (Hombr. and Jacq.). 
This description was drawn up by MM. Jacquinot and Lucas from 
the figure in the Atlas of the Voyage)and the markings, which: they 
thought represented canaliculations, seem to me to be only bands of
